Abstract

The purpose of this study was to increase the microbiological quality and yields of goat cheese prepared at farm level. For this purpose, appropriate technologies for the cheese-making process were designed, using a curd tank heated by gas, and cheese knives adjusted to the tank dimensions. Moreover, a low-cost table for whey draining and PVC moulds, were designed. Variables assayed were milk pasteurization, utilization of lactic acid starter by direct application, substitution of the kid rennet by commercial calf rennet, and cheese maturation for a one-month period. The control sample was goat cheese traditionally made by the small farmers. Processing and variables were evaluated by proximate chemical analysis, microbiological counts of aerobic mesophilic bacteria, total and fecal coliforms, and S. aureus; as well as by sensory evaluation of quality and acceptability. It was found that the cutting of curd with cheese knives significantly decreased solid losses in the whey. The addition of the starter and then the cheese maturation, as well as the use of the equipment previously described, increased the microbiological quality of cheese to standard sanitary regulation. Although pasteurization was the most effective treatment in...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
